The invention: relates to collectors for collecting particles which drop downwardly through an engine cylinder during a honing or grinding operation, and which particles 5 get intorthebearings, particularlythecrank shaft and, the connecting rod, and damage" the same. j

A further object isto provide a receptacle disposed within the crank. casing, and. engaging around the lower end, of the cylinderfor receiving the particles as they are removed, thereby preventing said particles froinentering the crank casing. V A further ob ect is to provide the upper ing, member for making a close fit of the receptacle, thereby preventing particles from.

passing over the upper edges of the receptacle. Also to provide thereceptacle with an air port, which air port will allow the exhaustand intaking of air, thereby preventing the receptacle from forming means which would: cause the honing device to become air bound within the cylinder.

A further object is to provide the lower end of the receptacle with a universally connected screw, which screw has threaded thereon a cone'nut which engages in an opposite sides of the crank casing, and an operating lever carried by said screw for forming means whereby the receptacle may be forced into close binding engagement with the lower end of the cylinder;

A further object is to provide means whereby the receptacle may be easily and quickly attached to the engine without varying the construction of the engine, and the marginal edge of the receptacle with a. packaperture of a bar detachably connected to receptacle adjusted upwardly or downwardcylinder showing the collector appliedthereto. p

Figure 2 is a vertical transverse sectional view through thereceptacle.

Figure 3 is'a. top plan view of the device,

Referring to the drawing the numeral 1 designates a cylinder of a conventional form of internal combustion engine and; 2' the upper section of the crank casing, which section is provided with outwardly extend ingfianges 3' at opposite sides thereofi It has been. found that when the honing or grinding device 4 is operated wvi'thin the cylinder 1 by any kind of movement, for instance a reciprocating: or rotary movement, particles of carbon and other material drop downwardly through the cylinder chamber 5 into the chamber ti of tlie crank casing,

consequently these particles eventually work into the bearings,.for instance the bearings of the crank shaft and connecting rods and damage the same To obviate this diiiir culty a receptacle 7 is providedawhich. is

preferably cylindrically shaped as shown,

and which receptacle has its upper edge provided with a gasket 8 which is preferably formed from felt, which will make a close engagement with the lower end 9 of the cylinder 1. One side of the receptacle 7 is provided with an air port 10, which air port extends upwardly and discharges at 11 ad-' jacent the upper end of the receptacle, and through which port air passes in both directions during the operation of the grinding or honing member thereby preventing compression of air upon thedownward movement of the honing member 4 and the forming of a vacuum upon the upward movement of the honing member, consequently the honing or grinding element 4 will move freely during the operation thereof. By terminating the airport 10 adjacent the upper end of the receptacle 7 danger of any of the particles being forced through the port, upon the downward movement of the honing member is obviated. It will be noted that the port 10 is spaced above the lower end of the receptacle 7 and above any particles which may collect in the receptacles, consequently danger of the particles being forced from the device is obviated.

Universally connected at 12 to the bottom of the receptacle 7 is a downwardly extending feed screw13, and which feed screw has threaded thereon a cone member 14:, which member 14: is rock-ably mounted in an aperture 15 in the horizontally disposed bar 16, therefore it willbe seen that the receptacle 7 when forced upwardly will accommodate itself to the bottom 9 of the cylinder and any irregularities therein incident to manufacture. V The lower end of the threaded screw 13 is provided with a crank 17 adapted to be grasped by the operator for rotating the screw and feeding the receptacle 7 upwardly or downwardly, and at which time the member 14 may be held against rotation if desired.

Bar 16 has one of its ends provided with a hook 18 which hooks over one of the flanges 3, and the other end with an upwardly extending member 19, which terminates above the other flange 3 and is provided with a thumb screw 20, which when threaded inwardly engages over the flange 3 thereby positively anchoring the bar 16 to the crank case section 2, and after the bar is placed ifthe same is not directly under the cylinder 1, the universal connections 12 and 15 will allow the receptacle 7 to assume its proper position in relation to the lower end of the cylinder.

From the above it will be seen that a particle collector is provided for use when varying the construction of the engines.

The invention having been set forth what is claimed as new and useful is 1. A grinding collector applicable to the lower end of an en ine cylinder having a crank casing exten ing below said lower end of the cylinder, a particle collecting receptacle engaging the lower end of the cylinder, a transversely disposed bar detachably-connectable to opposite sides of the frame casing and extending below the cylinder, a threaded shaft carried by the receptacle and extending through the bar, I

thereby and having outwardly extending flanges, a particle receiving receptacle engaging the lower end of the cylinder, a transversely dis osed bar, said bar having its ends detac ably connectable to the flanges, a threaded shaft, said threaded shaft extending upwardly through an aperture in the bar, a universal connection between thefshaft and the receptacle, a cone nut threaded on the shaft, said 'cone nut having a bearing in the aperture in the bar and an operating handle carried by the threaded shaft. p
